Brad Lander Leads Progressive Challenge to Incumbent Dan Goldman in NY-10 Primary

An Emerson College poll of 450 likely voters (May 16-17) gave former city comptroller Brad Lander 57% support, incumbent Rep. Dan Goldman 23%, and 20% undecided. The Democratic primary is on June 23.

Mayor Zohran Mamdani, a DSA member who won 2025 mayoral race, endorsed Lander. Lander, former NYC comptroller and 2025 mayoral candidate, is backed by Senators Bernie Sanders, Elizabeth Warren, Working Families Party and Public Advocate Jumaane Williams. Goldman, former assistant attorney general, is supported by Governor Kathy Hochul and House Minority Leader Hakeem Jeffries.

Emerson’s memo shows Lander leads voters under 40 by 73%-15% and seniors split 38%-31%; a Schoen Cooperman poll gave a narrower 47%-42% edge. Prediction markets price Lander’s win at 94% on Kalshi and 88% on Polymarket. The Emerson poll shows a 34-point lead versus a 5-point margin in the Schoen Cooperman survey. Critics say the Emerson survey may overstate youth turnout and undercount immigrant and senior neighborhoods where Goldman traditionally performs better; political scientists call Goldman an “insider.”

Lander’s campaign says it is “taking nothing for granted and continuing to run like we’re in the fight of our lives,” emphasizing grassroots organizing. Mamdani described Lander as a trusted ally who will deliver services.

Goldman adviser Simone Kanter called the Emerson poll inaccurate, arguing it assumes a turnout pattern like Mamdani’s mayoral election and ignores Goldman’s support in Chinatown, Lower East Side, Sunset Park and Borough Park. Political scientists label Goldman an “insider” and note the poll may overstate youth turnout while undercounting immigrant and senior neighborhoods.
